Download or read book Gemstone Enhancement written by Kurt Nassau and published by Butterworth-Heinemann. This book was released on 1994 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of Nassau's important work on the methods of modifying and enhancing gemstones and of treatments available to enhance the colour and appearance of gemstones. This includes various types of irradiation and heat treatment, colourless impregnations, bleaching, dyeing, diffusion and other processes. Some of these processes date back at least two thousand years; others are of quite recent origin. The book covers such advances as glass and plastic filling of diamonds and other gemstones, the large expansion in the use of both heat and irradiation treatments and the efforts to keep up identification procedures with the advances in treatments. Gemstone Enhancement is written for gemmologists to simplify their work: by knowing the details of the possible treatment techniques, the treatments that have been applied to the gemstone under study can be more readily recognized. Collectors, dealers, jewellers, appraisers, pawnbrokers and others interested in gemstones will also gain added insight from knowing the range of possible treatments. All the fundamental concepts are covered, so only a general knowledge of gems is required of the reader.

Book excerpt: Gemmology is a text for students preparing for the Gemmological Association's Preliminary and Diploma examinations. The book is more expansive and up-to-date than the author's earlier book, Beginner's Guide to Gemmology. The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward understanding gemmology after which cleavage, parting, and fracture are done. A gemstone's durability and hardness and how the latter influences engineering tests and the mining techniques are compared. An important test technique to identify unmounted stones is the measure of specific gravity using displacement measurement methods and hydrostatic methods. After more descriptive details are given in identification of gemstones, whether these are synthetic or simulants, through a comprehensive explanation of the materials found in these other gemstones, the fashioning, through shaping or polishing, of gemstones is explained. Emphasis is given on the critical angle in which light rays pass in different rock densities, and then the cutting styles, gemstone polishing, and grading are discussed. Students studying for the Gemmological Association's Preliminary and Diploma examinations, jewelers, lapidarists, and diamond cutters, as well as those engaged in the hobby of gemmology, will find this book helpful and full of information toward their endeavors and hobbies.

Download or read book Gemstones written by Michael O'Donoghue and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gemstones is the first attempt in English to bring together the geological, mineralogical and gemmological developments that have taken place during the last thirty years. Though there have been many gemstone books published in that time, most have been concerned, understandably and rightly, with the science of gem testing and have covered that area very well. Details of the geological occurrence of many of the classic gemstones, and of nearly all those which have only recently been discovered, have been less adequately dealt with. Coverage has been restricted to a number of papers in a wide variety of geological and mineralogical journals. Gemstones hopes to get the balance right. In the preparation of the book all the journals and monographs in the field have been consulted so that the book should stand for some years as the authority to which gemmologists and others turn in the first instance. Ease of reference and depth of coverage make Gemstones both a reference book and a bench book. Acknow ledgements I am grateful to Brian Jackson of the Department of Geology, Royal Museums of Scotland who read the manuscript and painstakingly indicated places where amendment or alteration was needed. I am also grateful to the publishers of the books on which the line illustrations are based. The colour plates present in the book derive from a number of sources, which I would like to acknowledge as follows. Plates 1, 4-15 and 17 Crown copyright reserved.
